If y = \(\frac{x}{x - 3}\) + \(\frac{x}{x + 4}\) find y when x = -2
A
-\(\frac{3}{5}\)
B
\(\frac{3}{5}\)
C
-\(\frac{7}{5}\)
D
\(\frac{2}{5}\)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
y = \(\frac{x}{x - 3}\) + \(\frac{x}{x + 4}\) when x = -2
y = \(\frac{-2}{-5}\) + \(\frac{(-2)}{-2 + 4}\)
= \(\frac{2}{5}\) + \(\frac{-2}{2}\)
= \(\frac{4 -10}{10}\)
= \(\frac{-6}{10}\)
= -\(\frac{3}{5}\)
